[0260]Preparation of Cationically Curable Silicone Resin
[0261]In a nitrogen stream, 161.5 mmol (39.79 g) of 2-(3,4-epoxycyclohexyl) ethyltrimethoxysilane (hereinafter referred to as “EMS”), 9 mmol (1.69 g) of phenyltrimethoxysilane (hereinafter referred to as “PMS”), and 165.9 g of acetone were placed in a 300-mL flask (reactor) equipped with a thermometer, a stirrer, a reflux condenser, and a nitrogen inlet tube, followed by temperature rise up to 50° C. The resulting mixture was combined with 4.70 g (1.7 mmol in terms of potassium carbonate) of 5% potassium carbonate aqueous solution added dropwise over 5 minutes, and subsequently combined with 1700 mmol (30.60 g) of water added dropwise over 20 minutes. Significant temperature rise did not occur during the dropwise additions. The mixture was then subjected to polycondensation in a nitrogen stream for 4 hours, while the temperature was held at 50° C.

Significant temperature rise did not occur during the dropwise additions. The mixture was then subjected to polycondensation in a nitrogen stream for 4 hours, while the temperature was held at 50° C.
[0270]A product in the reaction solution after the polycondensation reaction was analyzed and found to have a number-average molecular weight of 1799 and a molecular-weight dispersity of 1.57. The product had a T3...
